Since Linux 4.13 the value "powersave" in the x86_energy_perf_policy
program has been renamed to "power". Let's try both values when
applying the powersave profile.

Support specifying alternative Energy Performance Bias values.
The values are separated using the '|' character. For example,
if you have the following in your profile:
[cpu]
energy_perf_bias=powersave|power
then tuned will try to set EPB to 'powersave', and if that fails,
it will try to set it to 'power'.

Fix verification of Energy Performance Bias on Linux 4.13+.
In Linux 4.13, the value strings accepted by the x86_energy_perf_policy
program changed.

Previously verifying the value of a cpumask on systems with more than
32 cores always failed. There are two reasons for this:
1. When there are more than 32 cores, string comparison is done on the
cpu masks. This failed because the value read from sysfs contained
a line feed and was not stripped.
2. The cpumask value was not properly normalized when the value had multiple
non-zero comma separated parts, e.g. '00ffffff,80808000'

Catch exceptions not handled elsewhere to make applying, unapplying
and verifying a profile more robust.

I.e. one can now write:
[sysctl]
kernel.pid_max=>32768
And the kernel.pid_max will be set to 32768 if the current value is
lower or untouched if it is higher (i.e. it will be 32768 or higher).

A common source of confusion within tuned is the lack of suffix
on the readahead specification in the throughput-performance
tuned.conf. This confusion is resolved, in general, by comparing
the value, for example, to blockdev or lvdisplay output. Avoid
future end-user confusion by adding a comment to the
throughput-performance tuned.conf file, explaining that the default
is in KiB, and noting the allowance of a sector suffix as well.

The manpage already exists, but it's empty. So, this commit actually
adds the content. Also, update the AUTHORS, FILES and SEE ALSO sections.

Maybe this tool could be dropped, there are better alternatives like

You can now specify the python runtime using the PYTHON variable.
E.g. you can use
make PYTHON=python3 install
to install tuned modules to the python3 directory and rewrite
shebangs on executable Python files to use Python3.
For some reason this fixes the following errors during mockbuild:
sh: /usr/bin/python: No such file or directory
The versioned macro is provided by python-devel.
This fixes Pylint errors such as the following:
tuned/logs.py:39: [E1003(bad-super-call), TunedLogger.__init__] \
Bad first argument 'self.__class__' given to super()
This prevents infinite recursion errors, see
https://stackoverflow.com/a/18208725
This does introduce name duplication, but when we drop python2 support
in the future, we can use super() without arguments.
